Answer
(a) Three methods are:
- Passing electric field through a straight conductor/circuit.
- Passing electric current through a circular loop.
- Passing electric current through a solenoid.
(b) According to Fleming's left hand rule, the direction of magnetic is vertically downwards, as the current is flowing in clockwise direction.
(c) Right hand thumb rule.
